Ectopic liver tissue is a rare developmental anomaly that is not directly connected to the liver. We encountered ectopic liver tissue on the surface of the gallbladder wall during laparoscopic cholecystectomy. It has vasculature arising from the liver parenchyma and is classified according to its branching pattern. Ectopic liver tissue has been reported to occur in a variety of locations, and when encountered in surgery, it is clinically important to identify ectopic liver tissue with vascular supply to prevent unexpected bleeding. Ectopic liver tissue should be resected and examined histologically for the potential for malignancy when detected during surgical intervention.
